The invention discloses a method for manufacturing a preservation, refrigeration and transport case for fruits and vegetables. The key points of the technical scheme comprise: the reservation, refrigeration and transport case for fruits and vegetables is a rectangular foam plastic case; the bottom of foam plastic case is provided with reinforcing ribs, solid water and hard foam plastic plates. The four sides of the internal wall of the foam plastic case are vertically provided with attapulgite gelatin cold accumulation cases and attapulgite preservation corrugated boards, fruits and vegetables are placed in the space enclosed by the hard foam plastic plates and the attapulgite preservation corrugated boards and the soft foam sponge is covered on the fruits and vegetables. The upper foam plastic cover is placed on the soft foam sponge, and air vents are reserved on the upper foam plastic cover. The solid water can continuously and slowly release little water, and a certain humidity is effectively maintained in the transport case; therefore, the temperature in the transport case can be kept between 0 DEG C and 10 DEG C within 48 hours. The method for making the transport case is suitable for manufacturing the transport cases with refrigeration and moisture preservation effects for fruits and vegetables.
